A new holographic microscope allows scientists to see through the skull and image the brain. The new label-free deep-tissue imaging with the wave correction algorithm retrieves the fine neural network ...

Light microscope images of E. coli cells in transmitted light (left) and reflected light that picks up the red fluorescence of a dye staining the cells' DNA (right). In normal cells (upper panel), the ...

During the 1960s, researchers worked to overcome a debilitating feature of epifluorescence microscopy — background signals. Efforts began in both America and Czechoslovakia to do away with these ...
